19 Jan 2007 | | Abstract: | Heating of magnetized plasma by propagation of Alfven waves is calculated as a function of spectral density of magnetic field. The results can be applied to evaluate the heating power of solar corona at known data from satellite magnetometers. The heating power can be incorporated in global models for heating of solar corona and creation of solar wind. The final formula for the heating power is illustrated by model spectral density of magnetic field obtained by analysis of Voyager mission results. The influence of high frequency dissipative modes is also evaluated and it is concluded that for evaluation of total heating of corona it is necessary to know the spectral density of fluctuating component of the magnetic field up to the frequency of electron-proton collisions. | | Source: | arXiv, astro-ph/0701554 | | Services: | Forum | Review | PDF | Favorites | |
